Answer 3

ill try but i havent done it for a while

Answer 4

1?

Answer 5

or do you mean by divison

Answer 6

No, 1 / 4 = 0.25

We need whole numbers.

Answer 7

4/3

Answer 8

Err..no..we want a number that both 4 and 12 can multiply to get.

Answer 9

4 * 2 = 8

8 / 12 = 0.67

12 cannot get into 8, so 8 is incorrect.

Answer 10

4*9=36 and 36/12=3?

Answer 11

Yes, good, that's how you find them..but that's too big..there's a smaller number.

Answer 12

What's 4 * 3?

Answer 13

this is hard. um 4*6=24 and 24/12=2

Answer 14

4*3=12

Answer 15

12/12=1

Answer 16

Yes, you got it.

Answer 17

So 12 is the LCD here..you always want to first check and see if one of the denominators can get into the other.
